How to Check the BOM Weather Forecast for Melbourne—and Make Sense of It

The Bureau of Meteorology (BOM) is Australia's official source for weather forecasts and warnings. If you're checking the forecast for Melbourne, the useful question isn't only whether tomorrow's icon shows rain. It's whether the expected conditions, timing and uncertainty are clear enough to make a decision about travel, work or time outdoors.

This guide explains how to find a Melbourne forecast on the current BOM website or app, interpret rainfall information, check approaching rain and recognize when a daily forecast is not enough. It describes the service as available in October 2026, not a live forecast for a particular date.

Find the correct Melbourne forecast on the BOM website

1. Open the Bureau of Meteorology website, or go directly to the Melbourne forecast page.
2. Use the location search and enter Melbourne or the postcode of the place you actually need. Select the matching location in Victoria.
3. On the location page, choose Today for current conditions and the next hours, Days ahead for the seven-day outlook, or Past to review recent observations.
4. Check the forecast issue or update information before relying on a number that you may have seen in an older browser tab or screenshot.

If your plans are in a particular suburb, search that suburb instead of assuming that the Melbourne city-center forecast describes every neighborhood. Conditions can differ across the metropolitan area, particularly during passing showers and thunderstorms. BOM's BOM website instructions describes the location search, forecast tabs and hourly table.

Read today's forecast in the right order

Start with the daily summary: current and “feels like” temperature, forecast minimum and maximum temperatures, and the chance of any rain. Then open Show more about today for additional details, including the district forecast and sun and UV information.

Next, inspect the hourly forecast table. The website offers views for temperature and rain, wind, humidity, UV and cloud, or a combined display. This is where to look when a daytime maximum is less important than what is expected during a morning commute, a lunchtime event or the return trip home.

Read wind and gust information separately from temperature. A mild maximum does not guarantee comfortable conditions in an exposed location. If you need to make a high-consequence outdoor decision, check the applicable warning information as well as the hourly figures.

Understand Melbourne's rain percentage and rainfall range

Chance of any rain is not the percentage of the day that will be wet

A 60% chance of any rain means a 60% probability of measurable rain at the forecast location over the indicated period; it does not mean rain will fall for 60% of the day or across 60% of Melbourne. BOM generally uses a threshold of at least 0.2 mm for measurable rain.

Check whether the percentage applies to a whole day or a shorter time block. An hourly rain chance should not be read as if it covers the entire day.

The two rainfall figures describe different likelihoods

BOM updated its public rainfall explanation on May 21, 2026. Under that guidance, the lower number in a displayed rainfall range represents a 75% chance of reaching at least that amount, while the higher number represents a 25% chance of reaching at least that amount. For example, an illustrative range of 2–10 mm does not promise that exactly 2–10 mm will fall. It describes different probability thresholds, and the actual result could fall outside the range.

Read the rain chance and rainfall amounts together: the percentage helps with whether rain may occur, while the range helps you assess how much could fall. For the official explanation, see BOM explanation of rainfall forecasts, updated May 2026. Never treat either number as a guarantee that an outdoor event will stay dry.

Use rain radar for the next part of your day

When your decision depends on whether rain is moving toward your suburb now, open the BOM rain radar and weather maps. Search for Melbourne or the specific area, zoom to the location, and choose the Rain layer. The website's radar can help you inspect where precipitation has recently been detected and the direction it appears to be moving.

For additional context, select More weather to explore rain rate, radar reflectivity or estimated rainfall. These are different measures; a bright radar color is not itself a precise prediction of how much rain will reach your street. The BOM radar and map guide explains these layers and their limitations.

Do not confuse past radar observations with a future forecast. The BOM website's radar map does not provide the app's 90-minute future-rain view. If the rain is scattered, rapidly developing or associated with storms, recent radar movement may not reliably indicate what happens next.

Check the forecast with the BOM Weather app

The free, ad-free BOM Weather app offers hourly forecasts, a seven-day outlook, warnings and a weather map. Search for Melbourne or your suburb, then scroll to the daily forecast and select a day for more detail. The app also provides an hourly view for the next 72 hours and a rain map covering 90 minutes in the past and the future.

To check the map, select Map at the bottom of the app, then choose Rain or Warnings. You can set rain notifications for up to three locations. According to BOM, the rain notification is triggered when there is a 50% chance of at least 0.2 mm in the next half hour; it is an alert about a probability, not confirmation that rain has started.

Future rain on the app's map comes from forecast models, so it can differ from the observed radar picture and from conditions on the ground. The BOM app help and support describes those differences and the notification controls. If the app seems stale, check the selected location and refresh or consult the website rather than relying on an old display.

Check warnings before deciding that conditions are safe

Before going out during potentially disruptive weather, open BOM warnings and alerts. On BOM's website, the yellow warning triangle and the Current warnings area also provide access to active alerts. Review the affected area, hazard, validity period and recommended actions; a warning covering another part of Victoria may not apply to your location.

Warnings are especially important when severe thunderstorms, damaging winds, heavy rain, heat or fire weather could affect plans. A pleasant-looking daily icon is not a substitute for an active warning. If official advice calls for protective action, follow that advice rather than trying to infer safety from the radar alone.

Know whether you are seeing an observation or a forecast

The Past tab shows recent observations, while Today and Days ahead show forecast information. A measured temperature or rainfall total comes from a weather station; the forecast for a searched location represents expected conditions for a broader forecast grid. Those positions may not be identical. BOM explains this distinction in its BOM guidance on rainfall and observation locations.

Look at the station name and observation time when checking what has already happened. Do not use an observation from one site as proof that the same amount of rain fell at every address in Melbourne.

Which view should you use for each decision?

When should you check again or change your plan?

For a routine outing, the forecast is serving you well if you can identify the relevant suburb, the period you care about, the likely temperature and rain risk, and whether a warning applies. For tomorrow's plans, revisit the hourly forecast closer to departure. For plans several days away, use the seven-day outlook as an early signal and expect details to change.

Forecast uncertainty grows farther into the future, and local rain is harder to predict precisely than broad temperature patterns. If the forecast changes materially, rain cells develop unexpectedly or a new warning is issued, reconsider your timing, route or backup venue. BOM discusses these limits in its BOM guidance on forecast accuracy.

Finally, interpret forecast times in Melbourne, Victoria, not in the time zone of your phone's current location if you are traveling. Melbourne uses Australian Eastern Standard Time (AEST, UTC+10:00) outside daylight saving and Australian Eastern Daylight Time (AEDT, UTC+11:00) during daylight saving. See Victorian government time zone guidance if you need to compare times across regions.

Bottom line: Search the place you actually need, use Today for the next hours, Days ahead for the week, radar for approaching rain and warnings for safety decisions. The result to aim for is an informed plan with a realistic backup—not certainty about the weather.
